hi everyone

given one #bitlocker #0day is already out there, here's my own bitlocker 0day, I added it to my repo listing bitlocker attacks.

Introducing "ram leak": https://github.com/Wack0/bitlocker-attacks#ram-leak

As we all know, the boot environment allows booting from a ramdisk. This involves loading a file from disk into RAM, as expected.

However, "file" and "disk" can be arbitrarily chosen, and "disk" being a BitLocker encrypted partition is a supported scenario. Using another trick (same one used with bitpixie earlier) it's possible to get the keys derived without going through the legacy integrity validation checks too if relevant.

You can see where this is going. It's possible to leak any file from a bitlocker encrypted OS partition into RAM as long as you can get the keys derived (ie, TPM-only scenario).

The catch is that booting into the NT kernel marks that memory area as free so it could get overwritten there, but there are other ways to dump the memory area, and a PoC is included with my preferred method (it's only a PoC so just displays a hexdump of the first sector of the file)

The video shows successful exploitation in my test VM, it has secure boot enabled (you can tell because VMware shows an efi shell option on the boot menu when secure boot is disabled).

🐞 Linus Torvalds says AI-powered bug hunters have made Linux security mailing list ‘almost entirely unmanageable’

“So just to make it really clear: If you found a bug using AI tools, the chances are somebody else found it too. If you actually want to add value, read the documentation, create a patch too, and add some real value on *top* of what the AI did. Don't be the drive-by ‘send a random report with no real understanding’ kind of person. OK?”

RubyGems suspends new Signups after Hundreds of Malicious Packages are Uploaded.

RubyGems, the standard package manager for the Ruby programming language, has temporarily paused account sign ups following what has been described as a "major malicious attack."

"We're dealing with a major malicious attack on Ruby Gems right now," Maciej Mensfeld, senior product manager for software supply chain security at Mend.io, said in a post on X. "Signups are paused for the time being. Hundreds of packages involved – mostly targeting us, but some carrying exploits."
